[0001] The utility model relates to the field of electronic technology, in particular to a high-voltage limit test fixture. Background Art

[0002] In order to ensure the reliable quality of connector products, the products need to be tested during the quality inspection process. However, the applicant found that there are some problems in the test fixtures of current high-voltage connectors: 1. Conventional electrical testing uses connector plugs. The disadvantage is that the spring pins of the plugs directly pass through the GAP (gap) position of the terminal, which can easily cause the terminal to expand the PIN; 2. After plugging, the front end of the spring pin can easily pass through the GAP position of the terminal, which will cause the risk of terminal expansion.

[0003] Therefore, it is urgent to develop a high-voltage limit test fixture that can protect the terminal notch from being damaged. Utility Model Content

[0020] The following describes in detail embodiments of the present invention, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or components / elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present invention, and are not to be construed as limiting the present invention.

[0021] Figure 1 This is a three-dimensional diagram of a high-voltage limit test fixture provided by an embodiment of the present utility model; Figure 2 This is an exploded view of a high-voltage limit test fixture provided by an embodiment of the present utility model; Figure 3 This is a bottom view of a high-voltage limit test fixture provided by one embodiment of the present utility model; Figure 4 This is an AA cross-sectional view of a high-voltage limit test fixture provided by an embodiment of the present utility model; Figure 5 This is a partially enlarged cross-sectional view of a high-voltage limit test fixture provided by one embodiment of the present utility model; Figure 6 This is a partial enlarged view of a high voltage limit test fixture provided by an embodiment of the present utility model. Figure 1-6As shown, a high-voltage limit test fixture includes: a base 1 with a plurality of holes in the middle, a spring pin 2 inserted into the holes of the base 1, and a fixture shell 3 arranged above the base 1; wherein, the middle portion of the fixture shell 3 is provided with an inner frame hole 31, the inner frame hole 31 is provided with a fixture inner frame 4, and the middle portion of the fixture inner frame 4 is provided with a harness hole 41; the head of the spring pin 2 is provided with a limit ring 21.

[0022] Specifically, when testing the connector, the connector is inserted into the high voltage limit test fixture of the present application. Figure 5-6 It can be clearly seen that after the limiting ring 21 is set on the head of the spring pin 2, the end of the connector abuts against the limiting ring 21, so that the connector will not be over-inserted due to misoperation, nor will it cause invalid detection due to insufficient insertion, so that the terminal 6 to be tested is just in contact with the spring pin 2.

[0023] It should be noted that a harness hole 41 is provided in the middle of the inner frame 4 of the fixture. The shape of the harness hole 41 can be designed according to the specific shape of the connector to be tested. In the embodiment provided in this application, as shown in the accompanying drawings, it is a square high-voltage connector, so the harness hole 41 is also square.

[0024] According to the high-voltage limit test fixture of the utility model, a limit ring is provided at the spring pin to ensure that the connector is inserted to an appropriate depth, thereby preventing the spring pin from damaging the terminal and preventing insufficient insertion to prevent detection.

[0025] According to an embodiment of the present invention, a spring 22 is provided in the elastic needle 2 , and the spring 21 is connected to the head of the elastic needle.

[0026] Specifically, in order to reduce the stress when the connector is inserted into the jig and avoid hard contact between the terminal and the spring pin, a spring 21 can be provided at the head of the spring pin 2, thereby playing a secondary protection role.

[0027] According to an embodiment of the present invention, a latch key 5 is further included. A latch portion 32 is provided above the inner frame hole 31 , and the latch key 5 is provided at the latch portion 32 .

[0028] According to an embodiment of the present invention, the latch key 5 is provided with a latch hook 51 .

[0029] Specifically, the latch 5 is used to prevent the connector from loosening when the connector is inserted for testing. After the connector is inserted and the operation is confirmed to be correct, the latch 5 is buckled, and the hook 51 of the latch 5 can be buckled with the connector, thereby reliably connecting the connector.

[0030] The above embodiments are preferred implementation schemes of the present application. In addition, the present application can also be implemented in other ways. Any obvious replacement without departing from the concept of the present application is within the scope of protection of the present application.
